Despite the political angst, the doomsday predictions and a very rocky launch, the Affordable Care Act has enabled more than 8 million Americans to acquire insurance coverage through the public exchanges. Health insurance increases the probability that patients will access the medical care they need. And my colleagues at Kaiser Permanente are already seeing some positive stories emerging as a result. They've shared dozens of stories with me about patients with undiagnosed medical problems who are now receiving treatment. In particular, I enjoyed hearing about two new patients in Northern California who've benefited from being insured. They came in with life-threatening cancer.
